A new professional camera gimbal (tongue in cheek)

If you are here to look at a carbon fiber camera gimbal you have come to the wrong place.

However I wanted a small, nice, solid, light camera gimbal with roll and tilt with enough room for standard servos. I will break a lot of them. So I am not ready to invest a lot of money into one.

So I decided to draw one up myself and make one.

Here is the result. Nothing fancy, nothing pretty about it. Ok if I want to look exotic I can stain the wood and make it look like the Hawaiian Koa wood. However the reality is I made it out of birch ply.

No, it is not for sale. I will be glad to give you the DXF file so you can cut your own. You still have a lot of work to do after getting the wood parts. It is not for the beginners.

Any urges to go on a hole drilling frenzy to drop the weight a bit,i reckon a good 80 to 100g could be removed?.

you could easily lighten it by using lite ply if it was not done already. still, looks durable and should work well. should be rigid.

I will eventually drill out the roll cradle a little. I don't believe in drilling out holes. That just makes it weaker. However this is a bit over built so I can afford to lose a bit of weight.

Yes, that was the debate. Poplar would have been lighter but I want to try birch first and see. Lite ply have a tendency to warp in this humidity.

I was actually looking for bamboo as landing gear material. Then I started thinking about using bamboo for the arms. Now I may have to think about bamboo for camera gimbal!

I have used bamboo as landing skids before and it worked great. I was in China test flying a twin cylinder engine and they outfitted this high wing plane with a bamboo skid. The landing field was just a wide open dirt field and the bamboo skid worked very well because of the springiness.

I think bamboo will be great for multi rotor landing gear. I just have to find the proper size. There are lots of bamboo here and I have to harvest some. Buying them on eBay is ridiculous. They wanted an arm and a leg for just a little bit.

Direct drive will work only if the servo is super strong. Otherwise the inertia will cause a lot of oscillation.

I have some timing pullys so could do the belt, but that will add weight. have to see if I can lathe it down lighter. 2:1 ratio. I was thinking of direct drive just on the tilt, but may be not even that. belt drive would be smoother anyway.

I do think bamboo would make good LG. get her done.
